IL1B and hydrops fetalis: We did note a statistical decrease in IL-1β when comparing HF + CON + PRO to HF + CON (p = 0.041) and HF + DEP (p = 0.005) using an unpaired t-test (Additional file 3: Figure S2); however, could not perform a two-way ANOVA due to the HF + DEP + PRO group IL-1β measurements being below the standard curve.
